par2 is able to search the files matching a "wildcard" string given on the
commandline. This is not documented but I noticed it while I was trying to
modify the source code. Thus:
* It is possible to use par2 with any set of files, contrary to what was
said in the previous email (for example by specifying '*' in the directoery
where only the files concerned are)
* This is not always practical and it would still be nice to be able to
specify a long explicit list of files (for example for use in a script).
* The wildcard matching is neither documented nor mentioned anywhere as far
as I know. The usage message should mention it (it is displayed by the
function CommandLine::usage defined in the file commandline.cpp) as well as
the man page, since the feature can lead to an unexpected behaviour if a
file name specified on the command line unintentionaly contains a wildcard
character.
* The matching behave in a rather strange way as the following example shows
(`file' is not matched!). The wildcard matching is done by the function
DiskFile::FindFiles defined in the file diskfile.cpp. It should be either
documented thoroughly or behave as if the matching was done by the bash
shell itself.
